Configuring and Managing File System Storage Libraries
12c Release 2 (22.214.171.124.0)
This guide provides an end-to-end example for how to use Oracle Enterprise Manager Ops Center.
A storage library stores all the metadata for virtualization hosts and their virtual hosts, as well as the data that is the output of their operations. A virtualization host such as a global zone or a control domain relies on a storage library. In most cases, virtualization hosts are in a server pool, so each virtualization host uses the storage library associated with the server pool.
A storage library can use block storage or file system storage. When it uses a file system, the storage library can use a file system on the Enterprise Controller's system or a file system on an external storage device that is an NFS mount point. The file system on the Enterprise Controller is called a local file system and the file system on the NFS mount point is called a share.
A Sun ZFS Storage Appliance is unified storage, that is, it is capable of both file system storage and block storage. In this document, the Sun ZFS Storage Appliance is an NFS mount point and its shares are used for file system storage.
As a storage administrator, you create storage libraries to support server pools. These instructions create a NAS storage library, backed by a share on the Sun ZFS Storage Appliance.
See Related Articles and Resources for links to related information and articles.
You will need the following to set up and use this type of NAS storage library:
A Sun ZFS Storage Appliance that is a managed asset in Oracle Enterprise Manager Ops Center.
You must have the role of Storage Admin to create storage libraries.
The Sun ZFS Storage Appliance must be configured to be an NFS mount point and have available NAS shares. To learn how to set up an NFS server and client, see the Storage chapter in the Oracle Enterprise Manager Ops Center Feature Reference Guide.
These are the tasks for setting up a NAS storage library:
After you create the storage library, you associate the storage library with a server pool or virtualization host.
The NAS share is a file system on a NAS storage device. You can view the shares on a storage appliance from the Oracle Enterprise Manager Ops Center user interface.
Expand Assets in the Navigation pane.
Click All Assets to expand the section.
Click on the NAS storage server in the Storage section.
In the center pane, click the Storage Shares tab.
View the shares and identify with capacity to support one or more virtualization hosts.
After you have identified the physical storage for the storage library, you create the storage library in Oracle Enterprise Manager Ops Center.
Expand Libraries in the Navigation pane.
In Storage Libraries, click File System Storage.
Click New NAS Software Library in the Actions pane.
Enter a name for the library and a description. For example, identify how the new library will be used.
At this point, you could associate a server pool with the new storage library, if the server pool exists and you know the server pool will use the storage library. In these instructions, the storage library is created for use by any server pool, click Next without making a selection.
For the type of service, accept the default option, Share exported from a managed storage asset.
Click the Asset drop-down list to see the available storage devices. Select the same NAS storage server as you did in the previous procedure.
Click the Exported Share drop-down list to see the available shares for the NAS storage server. Select the share you identified in the previous procedure.
Click Next button to review our selections for the new storage library. Click Finish to submit the job.
When the job is completed, you can see the new storage library in the Libraries section of the Navigation pane in the Filesystem Storage section.
Because the storage library is not associated with any server pool or virtualization host, the storage library is not mounted and Oracle Enterprise Manager Ops Center has limited information about it. The Summary tab reports the size as -2 MB and the state as UNKNOWN. After the storage library is associated with a virtualization host or server pool, the size of the storage library is accurate and all actions for the library are enabled.
The storage library is available for any virtualization host or server pool. Select a server pool or virtualization host and then use the Associate Libraries action.
